3 Claims. (Cl. 206-47) This invention relates to pads and in particularto composite disposable cleaning or polishing pads.

This invention is designed .to overcome many of the disadvantages of thecurrent cleaning and polishing pads and also to provide cleaning orpolishing pads which are capable of uses not contemplated by padscommonly in'use, as set forth hereinafter. The present invention isdesigned especially for cleaning automobile windows. Automobile windowsare frequently dirtied and smeared by dust, mud, oil, grime and bugs.Such a condition of the windows makes driving quite hazardous,particularly at night, and endangers the lives of the occupants of theautomobile as well as others who might possibly be involved in anaccident caused by faulty vision through the automobile windows. usefulin cleaning or polishing of materials such as glass, cloth, paper,leather, metal, wood, and the like.

The cleaning or polishing pads commonly in use are dependent upon aseparate supply of cleaning or polishing compound. The devices in commonuse for cleaning automobile windows are dependent upon a supply of waterwhich may not be available readily in an extended trip, especiallyshould the trip necessitate travel through relatively unpopulated areas.However, the cleaning pad in one embodiment of this invention is notdependent upon a separate supply of cleaning fluid or cleaning compound,nor upon an outside source of water and hence is ideally suited for usein the cleaning ofautomobile windows under all kinds of conditions andin all locations.

Likewise, many of the polishing pads now in use are also dependent uponan auxiliary supply of polishing compound. Such auxiliary supplies arenot desirable since the polish containers fail to be air tight once theyhave been opened and hence the polishing compound becomes deterioratedand loses its effectiveness. However, the present polishing pad is not,dependent upon such auxiliary supply of polish and hence the polishingcompound is not subject to deterioration.

Also, this invention provides a compact shoe polishi ing pad capable ofbeing packed conveniently in a suitcase for use while traveling withoutsoiling clothing placed adjacent thereto andwithou't the necessity of aseparate kit to house the shoe polish equipment.

in general the present invention contemplates a composite disposablepad, comprising an applicator pad and a bufiing or drying pad separatedby a fluid-impervious barrier sheet which extends beyond the edges ofthe pads. This barrier sheet is sealed at its marginal por.

tions to fluid-impervious sheets covering each of the pads to therebyform envelopes for each of the pads. The applicator pad preferably isattached to the interposed barrier sheet, while the other pad, thebuffing or drying pad, may be free in its envelope.

The applicator pad is used to apply a cleaner or polish to a surface tobe treated. The buffing or drying pad is used as a bufiing pad to buffthe surface to which The composite pad is also polish has been applied,or used as a drying pad to remove the dirt and grime loosened by thecleaning com-,

' erably located between the applicator pad and the barrier sheet.

The two fluid-impervious envelopes prevent the passage of fluidstherethrough and hence prevent the deterioration and loss of thematerial to be applied either when the applicator pad contains thematerial or when it is contained in the frangible capsule which might bebroken accidentally. In addition, the envelopes prevent the soilage ofboth pads prior to their usage. The fluidimpervious barrier sheetprevents the passage of the cleaning or polishing compound from theapplicator pad to the bufling or drying pad and hence maintains this padin its original condition prior to its use.

For cenvenience in gripping the composite pad, the envelope enclosingthe bufling or drying pad may be provided with a handle. This handle maybe formed by a pleat in the envelope.

The invention will be described further in connection with theaccompanying drawings which show several embodiments of the invention.These drawings are used as means of exemplification of the invention anddo not constitute limitations thereof. The invention is to be limitedonly to the scope of the appended claims.

Fig. 7 is an elevational view of the pad shown in Fig. 5, showing thehandle in a folded position and the envelopes in their sealed position.

in the embodiment shown in Figs. 1 and 2, the composite disposablecleaning or polishing pad comprises two pads 31 and 2, preferably ofcellulosic material such as cotton, cloth, fiufied wood pulp, or one ofthe newer highly swelling celluloses, placed back to back. These twopads are separated by a fluid-impervious barrier sheet 3 formed of heavywaxed paper, cellophane, thermoplastic material, or the like, extendingbeyond the edges of the two pads and lying between the pads in planeparallel thereto. The applicator pad ll preferably is attached to thebarrier sheet by suitable means, such as a mastic or by heat sealingwhen using a thermoplastic material as Patented Jan. 29, 1957 thebarrier sheet. Fluid-impervious covering sheets 4 and lie on the outersides of the pads 1 and 2 respectively and parallel thereto. Thesesheets are made of some suitable material, such as cellophane orhydroxyethylcellulose. The covering sheets 4 and 5 are sealed to thebarrier sheet 3 along its marginal portions whereby the two pads areenclosed in individual envelopes with the drying or buffing pad 2preferably being loose in its envelope. The applicator pad in thisembodiment contains a cleaning or polishing compound applied to the padby coating, impregnation, or the like.

Figs. 3 and 4 show a second embodiment of this invention whereinidentical elements have been designated with the same numerals employedin Figs. 1 and 2, with the addition of a character a after the numericaldesignations. in this embodiment there is a frangible capsule 6containing a cleaning or polishing compound, either with or without asolvent or dispersing agent placed be tween the applicator pad 1a andthe barrier sheet 3a.

In the embodiment shown in Figs. 5, 6 and 7, elements identical withthose in Figs. 1 and 2 have been designated with the same numerals withthe addition of the letter b after the numerical designation. Thecomposite disposable pad of this embodiment is provided with a handle 7which conveniently may be formed from a diagonal pleat in the coveringsheet 5b. This pleat may be folded so that it lies fiat against sheet51) for convenience in packing, as shown in. Fig. 7. This pleat may beunfolded, as shown in Figs. 5 and 6, so that it lies perpendicular tothe surface of the composite pad and serves as a handle during theapplication step. This pleat could also be formed in sheet 5'41 coveringthe drying or buffing pad 2a of the embodiment shown in Figs. 3 and 4,wherein a frangible capsule is employed.

The applicator pad should be fairly substantial and in a rather compactformto enable it to withstand the abuse occurring during application ofthe cleaning or polishing compound.

For ease of identification of the two pads, the envelope containing theapplicator pad may be tinted differently from that containing the dryingor buffing pad. This would be especially desirable in the embodimentwherein the applicator pad is impregnated and no handle is provided onthe envelope enclosing the drying or buffing pad to differentiate itfrom the applicator pad.

The impregnated composite pad, shown in Figs. 1, 2, 5, 6 and 7, is usedby removing the sheet 4 or 4b which covers the applicator pad 1 or 112.The applicator pad is moistened if necessary, depending upon the type ofcleaning or polishing compound with which it is pro vided, and thecleaning or polishing compound applied to a surface by gripping thedrying or bufling pad 2 or 2!), or by gripping handle 7 and rubbing theapplicator pad against'the surface. With such an arrangement thecleaning or polishing compound is applied readily to a surface, but thewater-impervious barrier sheet 3 will prevent the compound frompenetrating the bufiing or drying pad which is still enclosed betweenthe fluid-impervious barrier and the covering sheet for that pad; andthe hands of the user will not be soiled.

The cleaning or polishing compound is applied by the embodiment shown inFigs. 3 and 4 by squeezing the applicator pad in to crush the frangiblecapsule 6 and then removing the sheet 4a covering-that pad. Theapplicator pad may be moistened if the capsule does not contain asolvent or dispersing agent and if moisture is desirable. The cleaningor polishing compound is then applied to the surface to be cleaned orpolished by gripping the drying or buffing pad 2a which is stillenclosed in its envelope and rubbing the surface to be cleaned orpolished.

After the cleaning or polishing compound has been applied to thesurface, thesheet 5, 5a, or 5b covering the drying or buffing pad isremoved and the pad taken out of the envelope for use in removing thedirt and cleaning compound from the surface or for use in buffing thepolish on the surface. After the cleaning or polishing operation, bothpads may be disposed of.

While the invention has been described in connection with the aboveembodiments only, it will be understood that various changes may be madein the details of con struction without departing from the invention orsacrificing any of the advantages thereof.
